+# 🚀 快捷部署指南
+
+本项目提供了 Windows 和 macOS 的一键启动脚本，方便快速部署到局域网。
+
+---
+
+## 📦 前置要求
+
+### 必须安装 Node.js
+
+- **macOS**:
+  - 官方下载: https://nodejs.org/
+  - Homebrew 安装: `brew install node`
+
+- **Windows**:
+  - 官方下载: https://nodejs.org/
+  - 建议下载 LTS（长期支持）版本
+
+---
+
+## 🍎 macOS / Linux 使用方法
+
+### 方法一：双击运行（推荐）
+1. 找到项目文件夹中的 `启动服务器.sh`
+2. **双击**运行（系统会自动使用终端打开）
+3. 如果提示权限问题，请使用方法二
+
+### 方法二：命令行运行
+```bash
+# 1. 打开终端（Terminal）
+# 2. 进入项目目录
+cd /Users/apple/Documents/cursor/三合一页面
+
+# 3. 运行脚本
+./启动服务器.sh
+```
+
+### 方法三：直接拖拽
+1. 打开终端（Terminal）
+2. 拖拽 `启动服务器.sh` 到终端窗口
+3. 按回车
+
+---
+
+## 🪟 Windows 使用方法
+
+### 方法一：双击运行（推荐）
+1. 找到项目文件夹中的 `启动服务器.bat`
+2. **双击**运行
+3. 会自动打开命令提示符窗口
+
+### 方法二：右键管理员运行（可选）
+1. 右键点击 `启动服务器.bat`
+2. 选择「以管理员身份运行」
+3. 点击「是」允许运行
+
+---
+
+## 📱 如何访问
+
+脚本启动后，会显示访问地址：
+
+```
+📍 本机访问: http://localhost:8080
+📍 局域网访问: http://192.168.2.9:8080
+```
+
+### 本机访问
+- 在启动服务器的电脑上打开浏览器
+- 输入: `http://localhost:8080`
+
+### 手机/平板访问
+1. 确保设备连接到**同一个 WiFi**
+2. 打开浏览器
+3. 输入局域网地址（如 `http://192.168.2.9:8080`）
+
+---
+
+## ⏹️ 如何停止服务器
+
+- **macOS / Linux**: 按 `Ctrl + C`
+- **Windows**: 按 `Ctrl + C` 或直接关闭窗口
+
+---
+
+## ❓ 常见问题
+
+### 1. 提示「找不到 Node.js」
+**原因**: 未安装 Node.js
+**解决**: 访问 https://nodejs.org/ 下载安装
+
+### 2. macOS 提示「权限被拒绝」
+**解决方法**:
+```bash
+chmod +x 启动服务器.sh
+```
+
+### 3. 手机无法访问局域网地址
+**检查清单**:
+- ✅ 手机和电脑是否连接到同一个 WiFi
+- ✅ 服务器是否正在运行
+- ✅ 电脑防火墙是否阻止了 8080 端口
+- ✅ IP 地址是否输入正确
+
+**macOS 防火墙设置**:
+1. 系统偏好设置 → 安全性与隐私 → 防火墙
+2. 点击「防火墙选项」
+3. 确保允许 Node.js 的网络连接
+
+**Windows 防火墙设置**:
+1. 控制面板 → Windows Defender 防火墙
+2. 高级设置 → 入站规则
+3. 新建规则，允许端口 8080
+
+### 4. 端口 8080 被占用
+**解决方法**: 修改 `server.js` 中的端口号
+```javascript
+const PORT = 8080; // 改成其他端口，如 3000
+```
+
+---
+
+## 🔧 高级配置
+
+如需修改端口或其他配置，请编辑 `server.js` 文件:
+
+```javascript
+const PORT = 8080; // 修改端口号
+```
+
+修改后重新运行启动脚本即可。
+
+---
+
+## 📞 技术支持
+
+如遇到其他问题，请检查:
+1. Node.js 版本: `node --version` (建议 v14 以上)
+2. 项目文件是否完整
+3. 防火墙设置
+
+---
+
+**祝使用愉快！** 🎉
